Several competing artificial compressibility methods for the incompressible flow equations are examined using high-order flux reconstruction method. The established method (ACM) of \citet{Chorin1967} is compared to alternative entropically damped (EDAC) \citet{Clausen2013}, as well an ACM formulation with hyperbolised diffusion. While former requires solution be converged a divergence free stat...

Although cumulonimbus (Cb) clouds are the main source of precipitation in south China, the relationship between Cb cloud characteristics and precipitation remains unclear. Accordingly, the primary objective of this study was to thoroughly analyze the relationship between Cb cloud features and precipitation both at the pixel and cloud patch scale, and then to apply it in precipitation estimation...

In this talk a review on the exclusive determination of |V cb | is presented. Updated values of this quantity obtained from B → Dℓ − ν ℓ and B → D * ℓ − ν ℓ decays are given. New measurements from B-factories are expected to come soon and the main challenges to improve the accuracy on |V cb | extracted from these decays are discussed.

We discuss the thermodynamic signatures for the topological phase transitions into Majorana and Weyl superfluid phases in ultracold Fermi gases in two and three dimensions (2D and 3D) in the presence of Rashba spin-orbit coupling and a Zeeman field. We analyze the thermodynamic properties exhibiting the distinct nature of the topological phase transitions linked with the Majorana fermions (2D F...

We report an artificial acoustic compressibility-near-zero medium made of a phononic crystal composed epoxy blocks arranged in square lattice. Its anisotropic effective density leads to linear cross its isofrequency contour the vicinity Brillouin zone center, as compressibility approaches zero. When Gaussian beam is normally incident on crystal, splitting effect achieved at frequency crossing p...

Two-dimensional materials can be crafted with structural precision approaching the atomic scale, enabling quantum defects-by-design. These defects are frequently described as “artificial atoms” and emerging optically addressable spin qubits. However, interactions coupling of such artificial atoms each other, in presence lattice, warrants further investigation. Here we present formation molecule...

A method suitable for computing fluid flow in the presence of moving boundaries is presented. In particular, the interaction of fluid with elastic walls is considered. The flow solver was developed based on artificial compressibility concept. The discrretization is done on unstructured tetrahedral meshes. A model of fluid interaction with elastic boundaries including boundary and mesh deformati...

The supercapacitive behavior of polyaniline/MnO2-carbon black (PANI/MnO2-CB), MnO2-CB nanocompositesand CB was studied. MnO2-CB made by the in situ direct coating method to deposit MnO2 onto CB; then PANI coating was coated on it. Morphology of the nanocomposite was studied by X-ray diffraction (XRD), Fourier transform...
